Reverse lights not working...?

[Holvinator]

:confused: They were working fine. I notice that they stopped working weeks after my gf and I installed a stereo in my car.Maybe one of the cables that runs behind the stereo its for the reverse lights & I never plugged it back in? if that is, what color is it?

I also noticed that Im leaking oil from the reverse sensor thats on the tranny, right before the speed sensor.In advance auto parts they call it "reverse switch something"
Please any input will be appreciate it. thanks

try tightening up the sensor, maybe it came loose. check the wires going to it, especially at the contact points on the sensor. if everything checks out then it probably needs to be replaced.
